An embarrassing slip-up – or a deliberately calculated prank – it’s the question that was on many minds when video surfaced of a man, who apparently failed to realise his headphones were not plugged in before watching pornographic material in a lecture theatre.

The video has gone viral since it was posted yesterday, garnering more than 2800 views – but more than a few YouTube users have cried foul.

“I'm gonna call it fake. Simply because no dumbass would watch porn with 100 people right behind him,” said (SBB) Blitz.

The video, apparently shot in an Australian lecture theatre, shows a lecture interrupted by loud, ecstatic cries coming from what appears to be a student laptop.
